Answer: 14.0 km/h

Step-by-step explanation:

First find the distance that both Ade and Kali travelled. Use the time and speed of Ade to find this out:

Distance = Speed * Time

= 15 * 2

= 30 km

Kali took 2 hours 15 minutes to travel 30km. Her speed is therefore:

= Distance / Time

Convert the time to decimal:

Mixed fraction = 2¹⁵/₆₀

= 2¹/₄

Decimal = 2.15 hours

Average speed = 30 / 2.15

= 13.95

= 14.0 km/h

Use absolute value notation to represent the distance between x and 8 is no more than 4
ivanzaharov [21]
The distance: use absolute value
Between x and 8: x-8

The distance between x and 8: | x-8 |

“is no more than” means it can be that or be less than that, so use ≤

The distance between x and 8 is no more than 4

| x-8 | ≤ 4

My brain stopped. I need help
Alisiya [41]

Answer:

x = 99°

y = 91°

Step-by-step explanation:

For Cyclic quadrilateral, the sum of the opposite angles = 180°

Let's find x :-

x + 81° = 180°

x = 180 - 81

x = 99°

Let's find y :-

y + 89° = 180°

y = 180 - 89

y = 91°

Hope this helps you !
